Handling with VIPA data handling blocks Manual BG41/BG42/BG43
4-22 Rev. 99/49
4.1.7.3 FB37 (SYNCHRON) from firmware 401xV50 and all of 4118 for 3964(R)
This data handling block prepares the interface building block for the operation of the procedure
3964(R).
The data handling block must be loaded in all start branches (OB20,21,22) for each interface
channel to be used. If 2 channels are used with the procedure 3964(R), this data handling block
must be loaded twice.
The data handling block has formal operands. Several operating parameters are to be set through
these formal operands. They are only directly addressable.
The following parameters are to be transmitted when loading FB37:
Des. Format Explanation
ADRE KH Address set with the DIL switches
SSNR KF Interface number 1,2,3
BAUD KF Baud rate code 1...11 (10 = 9600Baud)
FORM KM Transmission format:8bit,even parity,2 stop
PRIO KF 0=low, 1=high priority
BLOC KF Block size in bytes (always even-numbered!)
ZVZ KF Character delay time (value*10ms)
QVZ KF Acknowledgement delay time (value*10ms)
PAFE MB Byte for the output of a wrong number
NEUS M Blocks the building block
Tab. 4-10:List of parameters for the loading of FB37
The following details are necessary for the abovementioned parameters:
ADRE
Input of the physical start address, under which the building block can be
accessed by the PLC. This start address can be set with the DIL switches S1 and
S2 (see chapter 5).
SSNR
The interface number1, 2 or 3 is to be given.
BAUD
Different baud rates can be set by inputting the respective codes. With the plug
connector J11 on the building block, an optional baud rate of 150 to 38400 baud
can be set. In order to achieve this, J11, which has a baud rate of 75 to 19200
baud in its delivery state, must be replugged.
